Current perception threshold testing in chronic ankle instability

Abstract Background Damage to sensory input is an underlying pathology of chronic ankle instability (CAI). Therefore, it necessary evaluate the function patients with CAI. The present study quantitatively evaluated nerve in CAI and healthy controls using current perception threshold (CPT) measurements, as well influence sex, age, body mass index (BMI) on CPT values relations between frequencies. Methods Fifty-nine subjects 30 participated this study. at anterior talofibular ligament region were recorded injured uninjured sides both control group. Between group differences compared. age BMI was evaluated. Correlations different frequencies also studied. Results There no significant height, weight or groups. did not show a difference by sex. significantly correlate BMI. Compared group, had higher under 250-Hz 5-Hz electrical stimuli; groups ( p < 0.01), effect size large. No observed 2000-Hz stimuli. correlations (p especially 250 Hz 5 Hz. Conclusion revealed increased thresholds 250-Hz- 5-Hz-related fibres ankles This increase may indicate dysfunction A-delta C fibres. Sex, impact values. frequencies, Level evidence III, case-control
